Why are events (event-driven approach) generally created? What is the benefit of asynchronous processing through Kafka?

The event-driven approach allows building systems where components interact through events, which increases flexibility and scalability. This reduces coupling between parts of the system — they do not wait for responses directly but react to events as they occur.

Asynchrony via Kafka offers several advantages:

• High throughput and reliable message delivery.
• The ability to process events at different times and in different components without blocking.
• Easy scaling of consumers and ensuring fault tolerance.

Thus, Kafka helps build reactive, fault-tolerant, and scalable applications.
